I'm wondering from a visibility point of view if is not better to have those buttons at the top of each thread page. Not sure, but it might affect in a negative way the SEO rank, which might of forced Mike/Kier to drop them at the bottom of the page? Thanks for letting me know your input.
From the little I know about SEO, is important to show the first post content right after thread title. How but having the buttons placed right after the first post? It might make a nice separation from the OP. I'm think out loud.
